"The best way to kill a man:" Is 'Green Light Killa' connected to death of Milwaukee man?



MILWAUKEE/GALLATIN, Tennessee -- There is no evidence that the "Green Light Killa" ever took a life -- but Milwaukee police are still looking into the possibility a recent suicide here in Milwaukee may have been a homicide.

It turns out, the Green Light Killa may be a hoax.

Police in Gallatin, Tennessee say they've conducted a thorough investigation after a postcard was sent to a community college radio station -- and later forwarded to police.

"I found this is the best way to kill a man," the author writes.

It is signed: "Best Wishes, the Green Light Killa."

"He described an older gentleman that would be intoxicated -- lying them on the tracks, and just watching him being hit by a train," Lt. Chris Shockley with the Gallatin Police Department said.

Gallatin PD put out a bulletin to other law enforcement agencies nationwide.

"We sent that out just to make sure no other agency was investigating a case like that," Lt. Shockley said.

Jason Carroll



The bulletin caught the attention of Milwaukee police. MPD officials say they are awaiting surveillance video from Canadian Pacific to determine if the September death of Jason Carroll is actually a homicide.

Court documents reveal police believe there may be similarities between what's written on that postcard and Carroll's death.

Carroll's mother, Lavonne, tells FOX6 News her son had problems with drugs and alcohol. The Milwaukee County Medical Examiner's Office ruled his death a suicide.

But Lavonne says now, she's not so sure.

"It`s kind of unreal. You know -- did this actually happen?" Lavonne Carroll said. "I don`t know if it could ever be a clear-cut case."

Carroll's mother says her son did make suicidal statements in the past.

That postcard, sent to Gallatin police, was postmarked from Peoria, Illinois.

FOX6 News spoke to police there, who say they're not aware of any suspicious train-related deaths in their community.
